DETAILED DESCRIPTION

FIG. 1A illustrates a general perspective view of a Modular Structure10. The modular structure generally includes a deck system 12, a rigidwall system 14 and a roof system 16. The modular structure 10 is arigid-walled, modular, container transportable facility that is rapidlydeployable in a variety of situations. The modular structure 10 can beerected and fully functioning within days offering shelter, electricalservices, heating/cooling, and bathroom facilities. Assembled quickerthan pre-cast or stick built structures, the modular structure 10 can beerected for short or long term usage upon a variety of undesirableterrain features. Although a simplified structure is disclosed in theillustrated embodiment, it should be understood that a multitude ofvarious structures may be combined as modules to provide significantfacilities (FIG. 1B) which may be utilized for various purposes.

Referring to FIG. 2A, the deck system 12 is constructed from a multipleof deck unit modules 18. Each deck unit module 18 includes fouradjustable leg assemblies 20 attachable together by a lower truss 22L,22S between each leg assembly 20 so as to support a deck surface panel24. The deck unit modules 18 may be attached together to form a decksystem 12 of any desired shape and size. Preferably, each surface panel24 is a rectilinear four feet by eight feet panel, but deck surfacepanels 24 of any size may be usable with the present invention. The decksurface panel 24 is preferably of a laminated sandwich construction toprovide a rigid structure which is supported by the trusses 22L, 22S.

Preferably, the size of the deck unit module 18 defines the modularityof the modular structure 10. That is, each deck unit module 18 is abuilding block by which the other components such as walls are related.It should be further understood that the deck system 12 may be utilizedfor various purposes other than as a component of the modular structure10 such as a stage or bridge system.

Referring to FIG. 2B, each leg assembly 20 includes a primary leg 26, anintermediate leg 28 and a screw foot 30 each in telescopic relationship.Each leg assembly 20 may be telescoped independently to provide a leveldeck surface 24 irrespective of the underlying terrain (FIG. 2C).

The primary leg 26 is of generally tubular construction with an uppertruss attachment flange 32 and a lower truss attachment flange 34. Theupper truss attachment flange 32 and the lower truss attachment flange34 preferably each include eight truss attachment apertures 35 such thatthe lower truss 22L, 22S may be mounted at forty-five (45) degreeincrements about any leg assembly 20. Each lower truss 22L, 22S includesan upper and lower attachment hook 23 (FIGS. 2A and 2D) adjacent eachcorner thereof to selectively engage one of the truss attachmentapertures 35 of the upper truss attachment flange 32 and the lower trussattachment flange 34.

The uppermost end segment of the primary leg 26 includes a deckattachment plate 40. The deck attachment plate 40 preferably includesfour deck attachment apertures 42 such that four deck surfaces 24 mayinterface upon a single deck attachment plate 40 with fasteners f (FIG.3).

Coarse height adjustment is provided between the primary leg 26, and theintermediate leg 28 through a pinned interface 36, while a finer heightadjustment is provided by a threaded interface 38 between theintermediate leg 28 and the screw foot 30. The primary leg 26 includes aprimary pin aperture 44 while the intermediate leg 28 includes amultiple of intermediate pin apertures 46. Preferably, the intermediatepin apertures are elongated to facilitate adjustment and assembly (bestseen in FIG. 2E). A pin 47 is received through the primary pin aperture44 to engage one of multiple of intermediate pin apertures 46 to providethe coarse adjustment. The threaded interface 38 between theintermediate leg 28 and the screw foot 30 is preferably an ACME threadin which a wing nut 48 is selectively rotated to adjust the length ofthe screw foot 30 relative the intermediate leg 28.

The deck system 12 may be assembled in various arrangements such thatthe intersection of up to four deck unit modules 18 are attachedtogether with each leg assembly 20. That is, each leg assembly 20 mayconnect up to four deck unit modules 18—one for each deck attachmentaperture 42.

Referring to FIG. 4A, each deck unit module 18 of the deck system 12 isfurther connected to adjacent deck unit module(s) 18 by the rigid wallsystem 14. The rigid wall system 14 is also modular in that each wallmodule generally includes two support columns 50 and a rigid wallassembly 64 therebetween.

Referring to FIG. 4B, the support column 50 is a tubular generallyrectilinear member in cross-section having a center opening 55 and awall receipt slot 56A-56D on each side thereof (FIG. 4C). Each wallreceipt slot 56A-56D preferably includes a seal slot 58 therein toreceive seal 60 to assure a waterproof seal (FIG. 4D). Intermediate eachwall receipt slot 56A-56D is an auxiliary area 62A-62D which permitsrunning of conduits for electrical wiring, plumbing conduits as well asjunction boxes, switch boxes or the like.

Each wall receipt slot 56A-56D is generally defined along each side ofthe support column 50 with the auxiliary area 62A-62D located at eachcorner to define a frustro-triangular cross-sectional area having theapex thereof is located at the corner of the support column. The supportcolumn 50 includes a column deck plate 52 having a set of deck plateapertures 52A (FIG. 4C) which corresponds with the deck attachmentapertures 42 of the deck attachment plate 40 (FIG. 2B).

Referring to FIG. 4E, each rigid wall assembly 64 generally includes alower panel extrusion 66, a lower panel 68, a center wall extrusion 70,and an upper panel 72. The lower panel 68 and the upper panel 72 are ofa sandwich construction manufactured with an aluminum skin over a rigidurethane or polystyrene foam core to combine light weight with highstrength. The lower panel 68 and the upper panel 72 are preferably ofequivalent dimensions and are interchangeable. It should be understoodthat although a solid lower panel 68 and an upper panel 72 with a window74 are disclosed in the illustrated embodiment, various panel typesincluding window and non window panels are usable with the presentinvention. In addition, and prefabricated assemblies such as single doorassemblies 64S (FIG. 1B), double door assemblies 64D (FIG. 1B),multi-door assemblies 64M (FIG. 1) as well as other prefabricatedassemblies may also be installed between two support columns 50 toprovide various structure features.

The lower panel extrusion 66 is generally U-shaped in cross section witha central tab 74 (FIG. 4F). The center wall extrusion 70 is generallyI-shaped in cross section (FIG. 4G). The wall assembly 64 is readilyassembled by mounting the lower panel extrusion 66 to a long side of thelower panel 68, the center wall extrusion 70 to the opposite side of thelower panel 68 then the upper panel 72 to the opposite side of thecenter wall extrusion 70. The lower panel 68 and the upper panel 72 areinterference or friction fit into the respective lower panel extrusion66 and the center wall extrusion 70. It should be understood that otherresilient seals may additionally be provided.

Once the deck system 12 has been assembled, the rigid wall system 14 islocated thereon to define one or more structures S (FIGS. 1A and 1B).Each support column 50 is mounted to the deck system 12 such thatfasteners f are located through the deck plate apertures 52A of thecolumn deck plate 52, through the deck surface panel 24 and threadedinto the deck attachment apertures 42 of the deck attachment plate 40 inthe leg assembly 20 (FIG. 3). The rigid wall assembly 64 is then engagedwith one of the wall receipt slots 56A-56D (FIG. 4H) and central tab 74of the lower panel extrusion 66 is slid into the interface or gapbetween adjacent deck surface panels 24 (FIG. 4I). Such an interfaceadds further rigidity to the wall system 14 as well as structurallylocking each the rigid wall assembly 64 to the deck system 12.

The next support columns 50 is then mounted to the deck system 12 andthe rigid wall assembly 64 as described above. Such modular assembly isthen repeated to assemble the rigid wall system 14 upon the deck system12 to define the outer perimeter of the one or more structures S (FIG.1B). Such assembly is relatively rapid due in part to the light weightof the components, their interchangeability and the grid-like patternformed by the interface between adjacent deck surface panels 24 of thedeck system 12.

Referring to FIG. 5A, once the rigid wall system 14 has been assembled,the roof system 16 is located thereon to finish the exterior of thestructures S (FIGS. 1A and 1B). The roof system 16 generally includes aroof support structure 78 including a multiple of identical componentparts which are assembled together in a modular manner. The roof supportstructure 80 includes at least one of a roof truss 82, a peak purlin 84,a roof intermediate purlin 86 and a wall cap soffit 88.

Referring to FIG. 5B, the roof truss 82 is a generally triangular memberhaving roof truss end tabs 90A, 90B and a purlin attachment plate 94A,94B (also illustrated in FIG. 5D). The roof truss 82 is preferably sizedto fit within a shipping container and is approximately 16 feet inlength, however, trusses of other sizes are also usable with the presentinvention. Preferably, two roof trusses 82 are attached together (FIG.5C) to form a peaked roof.

The roof center attachment plate 92 and the purlin attachment plates94A, 94B include a multitude of key hole apertures 96. Each peak purlin84 (also illustrated in FIGS. 5E-5G) and roof intermediate purlin 86(also illustrated in FIGS. 5H-5J) include end attachment brackets 98which are engageable with the multitude of key hole apertures 96 of therespective purlin attachment plates 94A, 94B (FIG. 5A). Preferably, theend attachment brackets 98 are located at the end of, and on opposedsides of, the peak purlin 84 and roof intermediate purlin 86 such thatadjacent peak purlins 84 and roof intermediate purlins 86 sandwichvertical truss support members therebetween. The end attachment brackets98 are mounted to the purlin attachment plates 94A, 94B with anattachment stud 95 which engages the keyhole apertures 96 and a fastener(FIGS. 5K and 5L).

Referring to FIG. 6A, to assemble the roof support structure 78 to therigid wall system 14, the roof truss end tabs 90A, 90B are located intothe center opening 55 of two support columns 50 and are preferablyfastened in place with bolts or the like. Each roof truss 82 isattachable to an adjacent roof truss 82 at adjacent roof centerattachment plates 92 (FIG. 5A). That is, the roof truss end tabs 90A,90B are located into the center opening 55 of the support columns 50 andtwo adjacent roof trusses 82 are locked together at the roof centerattachment plates 92. The wall cap soffit 88 (FIGS. 6B and 6C) is thenmounted to the top of the rigid wall system 14 transverse to the rooftruss 82 along the length thereof such that each wall cap soffit tab 100is fitted within the center opening 55 of the support columns 50 (FIG.6D). Notably, the end wall cap soffit tab 100 is half the width of thecenter wall cap soffit tab 100 which completely fills the center opening55 of the support column 50 as the end wall cap soffit tabs 100 willinterface with other tabs such as those of the roof truss 82 or of anadjacent wall cap soffit 88. Once the roof support structure 80 isassembled to the rigid wall system 14, a multitude of roof panels 102are locate thereon (FIG. 7A).

Referring to FIG. 7A, the roof panels 102 are located between the peakpurlin 84 and the wall cap soffit 88. The roof panels 102 are retainedbetween a wall cap soffit edge 88E of the wall cap soffit 88 (FIG. 6E)and a raised center member 84E of the peak purlin 84 (FIG. 5G) andinterface with adjacent roof panels 102 at an overlapping roof panelinterface 104. That is, each roof panel 102 includes a male raised edge104 which engages within a female raised edge 106. The raisedoverlapping roof panel interface 104 covers a stepped interface 108 witha seal member 110 which slips into a slot 112 on an opposite side of anadjacent roof panel 102. The adjacent roof panels 102 essentially justslide into engagement with each other (FIG. 7D) to provide a watertightyet readily assembled interface. That is, each roof panel 102 isidentical with a first edge 102A and a second edge 102B. The first edge102A of one roof panel 102 engages a second edge 102B of an adjacentroof panel 102. The roof panels 102 are preferably attached to the wallcap soffit 88 with a multitude of roof panel clips 105—preferably threeper roof panel 102 which engage an edge of the wall cap soffit 88E (FIG.6C).

Referring to FIG. 8A, once the multitude of roof panels 102 are locatedon the roof support structure 78, a roof cap system 114 is mounted overthe edge interfaces of the roof panels 102 and the roof supportstructure 78. A multitude of ridge caps 116 (FIG. 8B) are located alongthe peak purlin 84 and fastened in place through screws or the likewhich engage the top center slot of the peak purlin (FIG. 5G). Trusssheeting 118, 120 is then fastened to the exposed side of each externalroof truss 82. Preferably, the truss sheeting 118, 120 is pre-attachedto the exposed side of the trusses with rivets or the like prior toshipment to further streamline on-site assembly. A multitude of roofgable end soffit caps 122A-122C (FIGS. 8C and 8D) are then locate overthe interface between the roof panel 102 which abuts the end roof truss82 and fastened thereto. The roof gable end soffit caps 122A-122C arepreferably attached to the truss sheeting 118, 120 on the side of theroof trusses 82 to minimize attachments through the upper surfaces.Finally, ridge joint caps 124 (FIG. 8E) are located over the interfacebetween adjacent ridge caps 116 and a roof cap end 126 (FIG. 8F) islocated at the apex intersection to cover the interface between theridge caps 116 and the roof gable end soffit caps 122C. A watertightsystem is thereby rapidly assembled.

Referring to FIG. 9A, an internal view of the roof system 16 illustratesa transport channel 130 located along the length of the wall cap soffit88 and along each side of the peak purlin 84 (FIG. 9B). The transportchannel 130 provides support and storage area for the running of wires,water supply conduits, and the like to provide an unencumbered floorarea. The wires, water supply conduits, and the like are simply locatedwithin the transport channel 130 then run down the auxiliary area62A-62D within the support columns 50 for communication to the desiredlocation. For example only, wires may be run from light fixtures L alongthe transport channel 130, down the auxiliary area 62A-62D within thesupport column 50 and to a junction box or switch box. Wiring andplumbing is therefore readily installed within the structure.Environmental conditioning transport conduits such as HVAC tubularconduits C may likewise be run along the transport channel 130 as wellas mounted directly to the truss beams 82 (FIG. 9C).

With reference to FIG. 10, any or all of the panels 24, 68, 72, 102 ofthe rigid wall system 14 and or the roof system 16 may provide ballisticresistance and are hereafter referred to as an armored panel 200. Thearmored panel 200 includes a non-ballistic resistant assembly 202 whichmay be used alone to form any or all of the panels 24, 64, 68, 72, 102of the rigid wall system 14 and or the roof system 16 where ballisticresistance is not required and with a ballistic resistant assembly 204bonded thereto where ballistic resistance is desired. It should beappreciated that non-ballistic resistant as defined herein providesessentially no resistance to projectiles.

The non-ballistic resistant assembly 202 generally includes a core 206which is sandwiched between skins 208. The core 206 may be manufacturedof a rigid urethane or polystyrene foam, honeycomb or other substrate.The skins 208 may be metallic or non-metallic and may be manufacturedof, for example, polymers, aluminum, composite laminates or otherrelatively thin material.

The non-ballistic resistant assembly 202 provides insulation qualitiesto the panels 24, 68, 72, 102 which facilitate usage in a habitablestructure. In one disclosed non-limiting embodiment, the non-ballisticresistant assembly 202 provides an R value of 13. It should beunderstood that various compositions may be utilized to form thenon-ballistic resistant structure 202.

The ballistic resistant assembly 204 is a hard armor composite sandwichstructure that generally includes a first ballistic resistant structure210 which defines the strike face, a second ballistic resistantstructure 212 and an adhesive layer 214 therebetween. In one disclosed,non-limiting embodiment, the adhesive layer 214 is a Methacrylateadhesive as manufactured by, for example, ITW Plexus, of Danvers, Mass.,USA Araldite of the Woodlands, Tex. USA, Loctite of Rocky Hill, Conn.,USA and others.

An adhesive layer 216 bonds the non-ballistic resistant assembly 202 tothe ballistic resistant assembly 204. In one disclosed, non-limitingembodiment, the adhesive layer 216 is a Methacrylate adhesivemanufactured by, for example, ITW Plexus, of Danvers, Mass., USAAraldite of the Woodlands, Tex. USA, Loctite of Rocky Hill, Conn., USAand others.

The first ballistic resistant structure 210 includes woven fabrics ofthermoplastic yarn and high strength glass fiber bonded with a highperformance epoxy such as that manufactured by Endurance Technologies ofSouth St. Paul Minn. USA. The first ballistic resistant structure 210may in one disclosed embodiment be between approximately 0.625 inches to0.755 inches thick.

The second ballistic resistant structure 212 includes fabrics of wovenaramid yarns impregnated with thermoplastic resin applied in layers. Inone disclosed, non-limiting embodiment, the thermoplastic resin is ahigh performance epoxy such as that manufactured by EnduranceTechnologies of South St. Paul Minn. USA.

In a method of manufacture, a double bag infusion with ahigh-temperature vulcanization thermoset resin is utilized to wet outthe fabric matrix then the product is cured via heated platens underpressure to increase crosslinking and thus strengthen the fiberreinforced matrix. It should be understood that various other methodsmay be utilized to bond each layer to the adjacent layer and thatvarious thicknesses may be utilized herewith. In one disclosedembodiment, the second ballistic resistant structure 212 may be betweenapproximately 0.25 inches to 0.525 inches thick.

The ballistic resistant assembly 204 is bonded to the non-ballisticresistant assembly 202 via a methacrylate adhesive. Since the armoredpanels 200 are mounted through, for example, extrusions 66, 70, the edgeof the armored panels 200 are supported and further reinforced forballistic protection through the extrusions 66, 70 (FIG. 4E) and orsupport columns 50 (FIG. 4A). That is, the edges of the armored panels200 are protected through the overlap of the extrusions 66, 70 andsupport columns 50 within which the armored panel is secured.

The high performance woven fiber with a tenacity over 8 grams per denierand high strength glass fibers which forms the strike plate of the firstballistic resistant structure 210 provides a very rigid but light impactsurface to reduce projectile velocity while retaining the strength toinitiate projectile deformation. These fibers are oriented to increaseoverall support and performance within the matrix. That is, the fibersare weaved into the fabric then the fabrics are cross-layered toincrease support in the matrix. Fabrics of woven, plain weave, aramidyarns in the second ballistic resistant structure 212 completeprojectile capture to ensure that no spall breaches the non-ballisticresistant assembly 202.

While many ballistic solutions utilize various sandwich structures thearmored panel 200 achieves lightweight structural applications withthermal insulation capabilities. The armored panel 200 has also beenshown to provide the ability to defeat high velocity rounds at aNational Institute of Justice Standard Level III as tested throughSouthwest Research Institute.

It should be understood that relative positional terms such as“forward,” “aft,” “upper,” “lower,” “above,” “below,” and the like arewith reference to the normal operational attitude of the vehicle andshould not be considered otherwise limiting.
